New to SPF and DKIM?

SPF identifies the servers allowed to send for a domain, while DKIM adds a verifiable signature to each message. DMARC uses their alignment results to protect your domain.

Monitor your SPF configuration continuously.

DMARCwise validates your SPF record and follows its resolution chain to catch syntax errors and DNS lookup problems.

Ensure your SPF record is syntactically correct and follows best practices with our Checks and Record validation features.

Inspect the full SPF resolution chain and spot records exceeding DNS lookup counts before they affect email delivery.

Detect DKIM selector gaps and stale records early.

DMARCwise extracts DKIM selectors directly from your DMARC reports, helping you identify DNS configuration issues that may prevent successful DKIM signature verification.
